The article discusses a study of the planet Jupiter by geochemist Thomas Kruijer of Lawrence Livermore National Laboratory in California while he was at the University of Münster in Germany and colleagues, suggesting that gas giants like Jupiter formed early on and that it may likely be responsible for the existence of planet Earth. Kruijer and colleagues focused on samples of rare iron meteorites to study Jupiter.
